Tried reporting via Spamcop. Both the SMTP sending host and all the links in the email are in the same class C, which Spamcop can't figure out a reporting address for. My suggestion would be to block all emails from avature.net in your SMTP server now.
@tw I can't really tell if reporting through it has any effect, tbh.
@tw It was pretty clear at one point back in the early '00s that my address was being listwashed as I reported stuff. That doesn't seem to happen now.
@freakazoid wow, Spamcop is still a thing? Neat!
